Cellular dysplasia in acquired cystic renal disease: comparison of histomorphometrically gauged nuclear parameters in normal kidneys, renal cell carcinomas and acquired cystic kidneys.
Nuclear parameters were assessed by computer-assisted image analysis in the cells of abnormal epithelial formations in the acquired cystic kidneys of two dialysis patients, the proximal and distal tubules of a normal kidney and two well differentiated renal cell carcinomas. One acquired cystic kidney contained many small clear celled foci and am 0.9 cm-size clear celled lesion and the second one a papillary microadenoma. The clear celled lesion was cytologically indistinguishable from the carcinomas. The histomorphometrically gauged nuclear parameters were maximal and minimal ferret diameters, averaged ferret diameter, aspect ratio, shape factor, area, volume and specific length and width. Statistical evaluation evidenced that the nuclear area, volume, aspect ration and shape factor allowed for the distinction between benign and malignant epithelial structures. The medians of the nuclear parameters of atrophic tubules, cysts, clear celled foci, papillary adenoma and clear celled lesion in the two acquired cystic kidneys deviation from those of normal renal tubules and in, increasing order of disparity, approached those of the carcinomas.
